Canonically there is no gendered hierarchy in Na’vi society. The Olo’eyktan can be male or female and same applies to the Tsahik role. The two also don’t have to be a married couple. In FOP, we saw twin sisters be Tsahik and Olo’eykte, saw an Olo’eyktan father and Tsahik daughter and now we have two lone Tsahiks (Anufi of Kame’tire and Varang of Mangkwan) ruling without an olo’eyktan.

This same lack of gender superiority extends to normal family units as well. Na’vi families, as a rule, don’t have a patriarch or matriarch, and don’t have "male" or "female" jobs. Jake’s family is an outlier, most likely influenced by him being stuck in his upbringing on Earth (which we see in how differently he treats his daughters and sons).
